C++ Cant' modify struct Component in details/viewport panel

[anonymous_user_5fd7f781]

Hey guys,

I’m trying to do something really simple, I have a struct with some component that I create in my constructor and attach it to the root. No problem so far, everything is created and moved in the origin of my Root. But When I go into my blueprint to move those component manually, I can’t access them.

USTRUCT(BlueprintType)
struct XROAD_API FXRoadVehicleSeat
{
	GENERATED_USTRUCT_BODY()

public:

	FXRoadVehicleSeat() {}

	FXRoadVehicleSeat(UBoxComponent* LocalDoorInteractionCollision,
		UArrowComponent* LocalExitVehicleArrow,
		EDoorPosition LocalDoorPosition,
		FName LocalSocketName,
		AXRoadPedestrian * LocalPedestrianOnTheSeat = NULL)
	{
		DoorInteractionCollision = LocalDoorInteractionCollision;
		ExitVehicleArrow = LocalExitVehicleArrow;
		DoorPosition = LocalDoorPosition;
		SocketName = LocalSocketName;
		PedestrianOnTheSeat = LocalPedestrianOnTheSeat;
	}

public:

	UPROPERTY(BlueprintReadWrite, VisibleAnywhere, meta = (AllowPrivateAccess = "true"), Category = "XROAD|Vehicle|Seats")
	UBoxComponent * DoorInteractionCollision;

	UPROPERTY(BlueprintReadWrite, VisibleAnywhere, meta = (AllowPrivateAccess = "true"), Category = "XROAD|Vehicle|Seats")
	UArrowComponent * ExitVehicleArrow;

	UPROPERTY(EditAnywhere, meta = (AllowPrivateAccess = "true"), Category = "XROAD|Vehicle|Seats")
	EDoorPosition DoorPosition;

	UPROPERTY(EditAnywhere, meta = (AllowPrivateAccess = "true"), Category = "XROAD|Vehicle|Seats")
	FName SocketName;

	UPROPERTY(BlueprintReadWrite, EditAnywhere, Category = "XROAD|Vehicle|Doors")
	AXRoadPedestrian * PedestrianOnTheSeat;

	UPROPERTY(BlueprintReadOnly, Category = "XROAD|Vehicle|Seats")
	bool bIsDriverSeat;
};

This is my stucture containing my two component I want to modify.

 // Seats properties
    
 UPROPERTY(BlueprintReadWrite, EditAnywhere, Category = "XROAD|Vehicle|Interaction")
 TArray<FXRoadVehicleSeat> VehicleSeats;

Here is my declaration of FXRoadVehicleSeat

AXRoadVehicle4W::AXRoadVehicle4W(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer)
{
	// Camera Setup

	// Create our FPS Arm spring component
	FPSCameraSpringArm = CreateDefaultSubobject<USpringArmComponent>(TEXT("FPSCameraSpringArm"));
	FPSCameraSpringArm->SetupAttachment(RootComponent);
	FPSCameraSpringArm->SetRelativeLocationAndRotation(FVector(0.0f, -32.0f, 128.0f), FRotator(0.0f, -5.0f, 0.0f));
	FPSCameraSpringArm->TargetArmLength = 0.0f;
	FPSCameraSpringArm->bEnableCameraLag = false;

	// Create our TPS Arm spring component
	TPSCameraSpringArm = CreateDefaultSubobject<USpringArmComponent>(TEXT("TPSCameraSpringArm"));
	TPSCameraSpringArm->SetupAttachment(RootComponent);
	TPSCameraSpringArm->SetRelativeLocationAndRotation(FVector(2.6f, 0.0f, 130.0f), FRotator(-15.0f, 0.0f, 0.0f));
	TPSCameraSpringArm->TargetArmLength = 400.0f;
	TPSCameraSpringArm->bEnableCameraLag = false;

	// Create the camera and attach it to the fps arm
	VehicleCamera = CreateDefaultSubobject<UCameraComponent>(TEXT("GameCamera"));
	VehicleCamera->SetupAttachment(FPSCameraSpringArm, USpringArmComponent::SocketName);
	VehicleCamera->SetRelativeLocationAndRotation(FVector(0.0f, 0.0f, 0.0f), FRotator(0.0f, 0.0f, 0.0f));

	// Setup Vehicle Seats

	NumberOfSeats = 4;

	for (int i = 0; i < NumberOfSeats; ++i)
	{
		// Door Collision
		UBoxComponent * Collision = CreateDefaultSubobject<UBoxComponent>(FName(*FString(GETENUMSTRING("EDoorPosition", (EDoorPosition)i) + "_Collision")));
		Collision->SetupAttachment(RootComponent);

		// Exit Arrow for the pedestrian
		UArrowComponent * ExitVehicleArrow = CreateDefaultSubobject<UArrowComponent>(*FString("ExitArrow_" + FString::FromInt(i)));
		ExitVehicleArrow->SetupAttachment(Collision);

		VehicleSeats.Add(FXRoadVehicleSeat(Collision,
			ExitVehicleArrow,
			(EDoorPosition)i,
			FName(*(GETENUMSTRING("EDoorPosition", (EDoorPosition)i))),
			NULL));
	}


	// Setup Anim Instance
	if (Mesh != NULL)
	{
		AnimationVehicle = Cast<UDcxVehicleAnimInstance>(Mesh->GetAnimInstance());

		if (AnimationVehicle != NULL)
		{
			AnimationVehicle->SteeringWheelAngle = 0.0f;
		}
	}
}

And finally my constructor where I initialize every Component.

Here is the result of this code. I still can’t access them, but if I’m putting them outside a struct It’s working as intended, I can modify them manually. So my question is what I am doing wrong, I put VisibleAnywhere or EditAnywhere for my component and even BlueprintReadWrite but I still can’t have any control over them in my Viewport or details panel.

Any feedback is welcome! Thanks!

So I’ll answer my own question, It’s not possible. You need to have your components inside your Actor. You can’t pass through a struct and not even have a TArray of your component. You won’t be able to modify your component in blueprint this way.
